Thank you for getting back to me.  I have been trying to figure
out how set the guest to log messages to the serial console.

I tried this command:

virt-install -n v1092 -r 512 --vcpus=1 --check-cpu --os-type=linux 
--os-variant=ubuntuhardy -v --accelerate 
-c /tmp/turnkey-lamp-2009.10-hardy-x86.iso 
-f /var/lib/libvirt/images/v1092.img -s 15 -b br0 
--nographics -x "console ttyS0"

When I do that, I get this output:

Starting install...
Creating domain... 

Connected to domain v1092
Escape character is ^]

And then it just sits there doing nothing.

My guess is the host is connected to a serial port, but the
guest does not know to set its console to that port.

Any suggestions?

Thanks,
	Neil
